A jQuery dependant snippet that adds support to styled checkbox/radio elements in IE8

initIE8Checkbox.js

function initIE8Checkbox() {
    jQuery('body').find('input[type="checkbox"] + label, input[type="radio"] + label').
        on('click', function (event) {
            var element = document.getElementById(event.target.getAttribute('for'));

            jQuery('body').find('input[name="' + element.name + '"]').removeClass('checked');
            jQuery(element).toggleClass('checked');
        }).each(function (index, element) {
            element = document.getElementById(element.getAttribute('for'));

            if (element.checked) {
                jQuery(element).addClass('checked');
            }
        });
}
